Maine Contractor License Requirements

01 The Maine model

Maine is not California, Florida, Arizona, Texas, Georgia, Nevada, Colorado, Washington or North Dakota. It has no statewide contractor license at all; the state credential is always an individual trade license, plus one transient-sales registration, and everything else is local.

• No statewide contractor license — verified absence — OPOR's complete professions list has no contractor entry, and LD 1226 died in the Senate. (Rule ME-NO-GC-LICENSE.) S-ME-OPOR-PROFESSIONS
• Electrical is an individual license — §1201 bars any electrical installation except by a board-licensed electrician; a master or limited electrician pulls the permit. (Rules ME-ELECTRICAL-LICENSE, ME-PERMIT.) S-ME-32-1201
• Plumbing is an individual license — §3302(1) requires a license for anyone engaged in plumbing; the master is the business-holding class, and a municipality may not issue a plumbing permit unless satisfied the applicant complies with ch. 49. (Rules ME-PLUMBING-LICENSE, ME-PLUMBING-PERMIT.) S-ME-32-3302
• Fuel is a Maine Fuel Board license — ch. 139 covers oil, solid fuel, propane and natural gas equipment; there is no statewide HVAC license. (Rules ME-FUEL-LICENSE, ME-NO-HVAC-LICENSE.) S-ME-FUEL-BOARD
• LOCAL permits are a separate system — the building permit is municipal (MUBEC above 4,000 residents) and the plumbing permit is municipal under 30-A §4215. (Rules ME-MUBEC, ME-PLUMBING-PERMIT.) S-ME-10-9724

02 Who regulates

03 State vs local

Maine splits the trade credential from the permit; the state boards decide who may work, the municipality issues the permit:

04 No statewide contractor license

A caller who reports holding a "Maine general contractor license" holds a credential Maine does not issue — it is a local or out-of-state credential. Do not answer a Maine construction question with "get a state contractor license".

05 The credential families

The 17 classification rows below are the complete state credential surface, across four families that are never collapsed:

06 Exemptions and owner rights

Maine's exemption lists are statutory and specific — the trade license is tested against the exception BEFORE it is asserted:

• Electrical — 13 statutory exceptions — §1201-A exempts industrial plants, low-energy installers, elevator mechanics, ch. 139 fuel technicians, ch. 49 plumbers for like-in-kind water pump/heater conductor work, ≤3 hp pump installers, wastewater plants, incidental light-fixture/switch work, and an owner in an EXISTING single-family dwelling they occupy (2025 c. 88). (Rule ME-ELECTRICAL-EXCEPTIONS.) S-ME-32-1201-A
• Plumbing — four exceptions — §3302(1) exempts public-utility employees, ch. 139 fuel technicians for same-room existing-piping hot/cold connections only, an owner-occupant of a single-family residence, and ch. 69-C pump installers (≤15 ft, same room, no new branch). (Rule ME-PLUMBING-EXCEPTIONS.) S-ME-32-3302
• Owner of a NEW dwelling — the §1201-A(13) exemption does not cover new construction: the owner must obtain a single-family dwelling certificate (§1102-D) before utility activation. (Rule ME-OWNER-EXEMPTION.) S-ME-32-1102-D
• Door-to-door exemption — a transient seller soliciting during the course of a municipal or state repair contract is exempt from the ch. 128 registration. (Rule ME-DOOR-TO-DOOR.) S-ME-32-14504

07 Bond and insurance

A consumer should still ask a contractor for a certificate of insurance — but Maine does not require it as a licensing condition, and no statewide bond exists to post, verify or renew.

08 Renewal

Every Maine trade license runs a two-year term based on the first-licensure date; the electrical classes additionally require continuing education:

Electrician CE: For Master, Journeyman, Limited and Journeyman-in-Training electricians the board requires Continuing Education of a 15-hour current National Electrical Code course as adopted by the board, on a two-year renewal cycle based on the first-licensure date. Chapter 120 adopted the 2026 NEC as the Maine installation standard for electrical installations commencing on or after 2026-07-01. S-ME-EEB

Reciprocity: The Electricians' Examining Board issues a license to a person licensed in another state or territory that has a reciprocity agreement with Maine and that person has passed that state's written examination and worked as an electrician a minimum of six years; the board presently has reciprocity agreements with New Hampshire and Vermont. For plumbers, 32 MRSA §3504-A requires the board to license an applicant licensed in another state or territory whose licensing standards and experience requirements are at least equivalent and which grants similar privileges to Maine licensees, and reciprocal licenses may not be denied on residency. S-ME-32-3504-A

09 State fees

The 14 verified board-published state fees — three board schedules plus the background check and the statutory permit/certificate cap. Local permit fees are deliberately withheld:

Full fees page → · The Electricians' Examining Board publishes a Master/Journeyman/Limited license fee of $150.00 and a biennial renewal fee of $150.00 (Senior over-70 $20.00), plus a $21.00 SBI/criminal background report fee; 32 MRSA §1203-A caps any one electrical fee at $150 biennially (permit and inspection fees excepted). A late fee of $50.00 applies up to 90 days after expiration; a license more than 90 days but not more than 2 years expired reinstates by paying the $150 fee plus a $100 penalty. S-ME-EEB-MASTER

10 Trade credentials and the board MOUs

• Electrical — the business is the individual master — there is no separate "electrical contractor" license: the business-holding credential IS the master electrician license, and a master or limited electrician pulls the permit. (Rules ME-ELECTRICAL-LICENSE, ME-ELECTRICAL-SCOPE.) S-ME-32-1201 S-ME-32-1102-C
• Plumbing — the business is the individual master — a master plumber engages in the plumbing business; a journeyman works under a master; a master/journeyman supervises at most 3 trainees. (Rules ME-PLUMBING-LICENSE, ME-TRAINEE-SUPERVISION.) S-ME-32-3302
• Plumber examinations have statutory pass marks — master ≥75%, journeyman ≥70% (§3501-A); the board contracts with PROV. (Rule ME-PLUMBER-EXAM.) S-ME-32-3501-A
• Fuel is the combustion/fuel-gas credential — a Maine Fuel Board license covers oil, solid fuel, propane and natural gas; the master class runs the business. (Rule ME-FUEL-LICENSE.) S-ME-32-18132
• The crossovers are narrow and bounded by MOUs — §1201-A exempts ch. 139 technicians "subject to the restrictions of the license as issued", and §3302(1)(B) exempts them from plumbing only for same-room existing-piping connections; the Fuel Board publishes MOUs with the EEB (mini-split heat pumps; hot-water/steam/warm-air) and the PEB (hot-water/steam systems). (Rule ME-FUEL-LICENSE.) S-ME-FUEL-BOARD
• Door-to-door home repair is additive — the ch. 128 registration is required IN ADDITION to any trade license, and a violation is a Class E (strict liability) or Class D (intentional) crime. (Rule ME-DOOR-TO-DOOR.) S-ME-32-14504

11 Solar

• No standalone solar license — verified absence — rooftop photovoltaics are ch. 17 electrical work, so a licensed electrician (with an electrical permit by a master/limited electrician) is the credential. (Rule ME-SOLAR.) S-ME-32-1201
• The only solar-specific provision — LD 1730 (P.L. 2025 c. 644, effective 2026-07-29) added 35-A §3475: a plug-in photovoltaic or battery system whose inverter output exceeds 420 W but is no more than 1,200 W per service address must be installed by a Maine licensed electrician on a dedicated circuit with a single receptacle outlet.
